Hi Everyone,

I am new to openflow and SDN. I have a very basic question regarding the network topology and placement of controller.

Does every switch/networking-device needs to be connected to a controller?

I have attached an image which has a simple topology with three switches S1, S2 & S3, and a controller connected to only S1.

Is it possible to have this topology with openflow 1.0?

I would really appreciate your help!

Thanks,
Ayush
